bareudp: Remove synchronize_net() in bareudp_sock_release().

Browse Source 
synchronize_net() in bareudp_sock_release() has existed since
day 1, commit 571912c69f ("net: UDP tunnel encapsulation module
for tunnelling different protocols like MPLS, IP, NSH etc.").

It was most likely copied from a similar tunneling device like
vxlan or geneve.

bareudp_sock_release() is called from dev->netdev_ops->ndo_stop(),
and synchronize_net() in unregister_netdevice_many_notify() ensures
that inflight bareudp fast paths finish before bareudp_dev is freed.

Let's remove the redundant synchronize_net() in bareudp_sock_release().
